The Bolsheviks sought to coordinate this new wave of revolution in the Soviet-led Communist International, while new Communist parties separated from their former socialist organizations and the older, more moderate Second International.

The Felicistas, the last major group of counterrevolutionaries, abandoned their armed campaign in 1920, and the internecine power struggles abated for a time after revolutionary General Alvaro Obregon had bribed or slain his former allies and rivals alike, but the following decade witnessed the assassination of Obregon and several others, abortive military coup attempts and a massive right-wing uprising, the Cristero War, due to religious persecution of Roman Catholics.
